The above classification of the Polynesian languages follows
the one made in Ethnologue:
Languages of the world (Grimes 1996; 13th edition), except
for the details mentioned below.

Niuatoputapu is here classified as a Wallisian language, and
not as an unclassified language within the Samoic-Outlier group, based
on the classification made by Grimes 1992 where Niuatoputapu is
considered to be genetically closer to the Wallisian language
Niuafo'ou than to any other language. However, since so little is
known about Niuatoputapu an exact classification is of course
impossible.

Tokelauan is here classified as a language in the Ellicean
subgroup, and not as the sole language in a Tokelauan subgroup,
which is based on information in Biggs 1971 and in
Ethnologue: Languages of the world (Grimes 1996; 13th edition)
stating that Tokelauan is very closely related to Tuvaluan
and that the two languages are mutually intelligible.

Napuka is here classified as a language, and not as a
dialect of Tuamotuan, based on the statement by P.H. Audrian
1919 (Notes sur le dialecte Paumotu) that Napuka is clearly
distinct from Tuamotuan, and also on my own field experiences of Napukan in
1993.

Reao is here classified as a language, and not as a
dialect of Tuamotuan, based on the statement by P.H. Audrian
1919 (Notes sur le dialecte Paumotu) that Reao is
incomprehensible to speakers of the Tuamotuan language,
and also on my own field experiences of Reao in 1993.

Rapa is here classified as a Tahitic language, and not as an
unclassified language within the Central Polynesian subgroup,
based on Biggs' 1971 statement that the language spoken on the island of
Rapa today is a variant of the Tahitian language. J.F.G. Stokes 1955,
however, claims that another language, clearly distinct from the other
Tahitic languages, was earlier spoken on Rapa; and Niko Besnier 1992
classifies Rapa as a Marquesic language. It may be then that there was a
now extinct Marquesic language - Old Rapa - spoken on Rapa before,
which is why I have (hypothetically) also included Old Rapa among the
Marquesic languages.

Moriori is here classified as a language, and not as a
dialect of Maori, based on the opinion held by many authors, for
instance Biggs 1971, that Moriori was clearly distinct
from Maori.
